Improvement in machines for making fishing-lines and other small cords



UNITED Simfree PATENT GFF-ion,

PETER BROOKS, OF NEW HAVEN, CONNECTICUT, ASSIGNOR TO THE NATIONAL LINE AND CORD COMPANY, OF SAME PLACE;

IMPROVEMENT IN MACHINES FOR MAKING FISHING-LINES AND vOTHER SMALLCORDS.

Speciiication forming part of Letters Patent No. 59, 120. dated October 23, 1866.

To all whom "it may concern:

Beit known that I, PETER BROOKS, of New Haven, in the county of New Haven, and State of Connecticut,have invented a new Improvement in Machinesfo'r Twisting Lines; and Ido hereby declare the following, when ytaken in connection with the accompanying drawings,

and the letters of reference marked thereon, to be a-full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in

. Figure 1, the-front view; Fig. 2, theside view; and in Figs. 3, 4, and 5, detached parts enlarged to illustrate the operation of my improvement.

My invention relates to an improvement in machinery for making small lines, such as fish-lines, Stc., and consists in a peculiar mechanism which forms both a twister and feeder; also, in a device fora stop-motion, which operates so that when either one of the several threads break the machine will be stopped.

To enable others skilled in the art to construct and use my improvement, I will procced to describe the same as illustrated in the accompanying drawings.

A A is a frame, which supports the oper-v ative mechanism of my machine; B, acupright driving-shaft, supported .in bearings C, and caused to revolve by the application of power to the pulley D. E, E, a-nd E, are spools, supported in fliers F, which said iiiers are caused to revolve by a belt, G, on the pulley H of the driving-shaft. The said spoolsE contain the thread from which the line lis to be formed, and the number of the spools and iliers must be the number of strands of which the line is to be formed.

l is the twisting apparatus, (shown enlarged in Fig. 3,) and is constructed and arranged as follows: To a cross-bar, K, a bearing, L, is fixed, through which a hollow shaft, a, passes,

, its upper end forming a yoke, M, which supports the feed-shaft N. The said hollow shaft a has attached to it a pulley, P. Within the hollow shaft a is placed a second shaft, d, to the upper end of which is fixed a bevel-gear, R, working in a corresponding gear, S, on the shaft N. To the lower end of the said shaft d is fixed a pulley, T, and below the said pulley T a flier, U. Poweris applied to the two pulone T being a little larger than the other, proportioned as hereinafter described, so that the shaft a, carrying the shaft N, is caused to revolve faster than the shaft d by so much as the difference in theirrespective pulleys. The gear-wheel R, therefore revolving with a less velocity than the yoke M, will, by its connection with gear S on the shaft N, cause the said shaft N to revolve upon its own axis slowly while being revolved upon the axis of the yoke M.

The three threads, from their respective spools E, are brought down, as denoted in Fig. 1, `,through a guide, f, (see Fig. 3-a top view seen in Fig. 4,) each thread passing through'a separate hole in the guide f. Thence the three threads are wound several times around the conical part of the shaft N, then passed down through the hollow shaft d, through the flier U, to a spool, Z, as seen in Fig. l. y

Power now being applied to the machine, the twisting apparatus is set in motion,.re volvingrapidly, twists the threads into asingle line, winding around the conical part of the shaft VN as fast as twisted, which draws or feeds the twisted line down to the flier, which revolves around the spool Z, winding the finished line thereon. The spool Z revolves with the flier, suflicient friction being applied thereto to retard its motion, so that the twisted line is wound thereon. This is the case also with the upper spools E, which revolve with their re-v spective iiiers, so asto draw the thread required therefrom. The feeding or conical part of the shaft N is made of the form shown, so that as the line twisted winds upon the conical part it will slip thereon, so as to retain nearly the same relative position.

The spool Z rests upon a bar, A', which said bar A is hung to levers B', which said levers rest upon cams D', which, bein g slowlyrevolved through connection with the driving-shaft, causes the spool Z to rise and fall as the line is wound from top to bottom and returning.

' Some classes of lines are required to be closer twisted than others. The closer or less oblique the twist the slower should be the feed. This effect is accomplished by changing the size of the pulleys l and T. Itis evident that were these two pulleys-of the same diameter, the feeding-shaft N would remain stationary upon its own aXis, whereas, by revolving upon the axis of its yoke at a greater velocity than that of the shaft d, the feeding-shaft N will be revolved by so much as the difference in the velocity of the yoke andthe shaft d. Therefore, to feed faster, diminish the diameter of the pulley P or increase that of the pulley T, or, what will produce the same result, make a like adjustment of the pulleys b and c on the driving-shaft.

.Another mode of adjustment is made by changing the feeding-shaft N, by inserting a smaller or larger cone, accordingly as the twist is to be closer or more open.

The second part of my invention, which relates to a stop-motion, is seen in Fig. 5. Above the guide f, I hang a lever, h, upon afulcrum, i, the other arm, l, operating upon a trip arranged in any convenient manner and position to disconnectthe powerfrom the driving-shaft. Each thread, as it passes from the spool to the thread-guide f, passes over a pulley, n, on the said lever h, as denoted in Fig. 5, holding the lever up in the position denoted in black, (the thread denoted in blue 5) but when, by accident or otherwise, the thread becomes too slack or broken, a counter-balance, t, on the lever h causes the lever h to fall forward, as denoted in red, in which movement the arm Zgoperates upon the trip and disconnects the power.

Having therefore thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is

1. The feedingbar N, arranged `upon the hollow shaft a, and combined with the hollow shaft d and the threadguide f, constructed and arranged to operate substantially in the manner and for the purpose herein set forth.

2. The lever h, in combination with the rcspective threads of which the line is formed, and the twisting apparatus, constructed and arranged to operate substantially in the manner and for thepurpose herein set forth.

PETER BROOKS.
